I’m watching a freecodecamp vid about Mojo. And the guy is talking about the Modular discord channel, which I can’t find for the life of me.
Perhaps it’s too much of a moving target right now. Tutorial from a few months ago, describe using Let to define constants, and now that’s not valid. Now you get… error: ‘let’ is being removed, please use ‘var’ instead. Although you would think version 24.3.0 would be more settled. However version 24… really? How can a language released in 2023 be at version 24? I’ve seen too many weird versions from other products, like this that make no sense.
Python, which has been around for decades… is only at version 3.10
bill@bill-MS-7B79:~$ python --version
